These are beautiful tanks. They make bathtubs like this, too.
Ha! I am working on the whole fish tank on each wall idea!
This is an idea that I would love to implement when my wife and I build a house, but I doubt I'll actually get to do it.
Back on topic: while I think the idea of the Zero Edge is cool, I don't know that I'll ever get one. Almost all of my tank ideas involve creatures that are really good at escaping, especially when you get into saltwater tanks.
